WaterPy - Water and Environment Tools in Python

##WaterPy: Water and Environment Tools in Python

WaterPy aims to develop a Python library for water and environmental engineering. This is a free library for any use.

Collaborations and contributions to the project with new modules or functions, improvement of the existing code, are most than welcome.

If interested, please contact or submit your Python code, with a file with the following information to be included in WaterPython blog:

• An explanation of the function to be included in the section "About" of the function page;
• A simple "sample Code" easily read;
• Finally, the expected "Result" .
• New modules water and environment can be created and included in the library.

WaterPython thank you in advance for your contribution and support.

• Get in contact with the project: http://waterpy.blogspot.com/
• Get the library at https://github.com/dmgsantos/WaterPy
• For any question or sugestion: dmgsantos@gmail.com
